Based on the collection and collation of material about Andromedids recorded in the history of China,as well as on some researches,five conclusions have been drawn. (1)Comet Biela projects a large number of particles 5 times before fission,while the law that the projection happens every 4 periods proves that the gravitational effect on Comet Biela is periodic.(2)The projection is in a forward direction so that the rocket effect is especially evident.At the same time,the cycle shortens continuously but unevenly...

Based on the collection and collation of material about Andromedids recorded in the history of China,as well as on some researches,five conclusions have been drawn. (1)Comet Biela projects a large number of particles 5 times before fission,while the law that the projection happens every 4 periods proves that the gravitational effect on Comet Biela is periodic.(2)The projection is in a forward direction so that the rocket effect is especially evident.At the same time,the cycle shortens continuously but unevenly for it shortens for 9 days every time the Comet returns,yet the orbital eccentricity doesn’t change.(3)After disintegration,the orbital width of meteoric dust is 10 million kilometers in 1798,and 5 8 million kilometers in 1885.The diffusion speed of the meteoric dust to the two sides of the orbit is 0 69 meter per second,while the separating speed of the second celestial body of the Comet is 7 meters per second.The former is one tenths of the latter.(4)Based on the statistical figures calculated by H. A. Newton about the density of a meteoric shower that happened in 1885,the densities and quantities of several large meteoric showers recorded in Chinese history have been estimated,including the estimation to the minimum of some confused concepts in ancient and folk accounts,such as stars falling like rain,beyond counting,innumerable and numerous.Along with the estimation for the meteoric densities and quantities of some special phenomena,such as the brightness of the sky which can cover that of the stars and moon,the shining phenomena looking like aurora,the sound produced by the atmosphere and the fear of the observer.(5)The sole scientific phenomenon of “the moon looks like falling off ”recorded in the history of China is explained incidentally.

对中国历史上关于仙女座流星雨的记载进行收集、整理和校勘 ,并在此基础上进行研究 ,得出 5项结果 :(1 )比拉彗星在分裂之前曾有 5次大量抛射物质 ,而这种抛射有四个回归周期一次的规律 ,证明引力效应对比拉彗星是周期性的。(2 )抛射方向都是向前 ,所以火箭效应非常明显 ;周期不断缩短 ,但不均匀 ,平均每回归一次缩短 9天 ;轨道偏心率不变小。 (3 )彗星碎解后 ,流星尘云分布的轨道宽度 1 798年为 1千万公里、1 885年为 580万公里 ;向轨道两侧的扩散速度为每秒 0 .69米 ,为彗星分裂后二彗星体的分离速度每秒 7米的 1 /1 0倍。 (4)以H .A .牛顿对 1 885年出现的流星雨密度的统计值为基础 ,对中国记载的几次最大的流星雨的密度和总量进行估算 ,包括对古代和民间记载的流星雨数的几种模糊概念 ,如星陨如雨、不可称数、无数、众多等 ,做出最低下限的估算 ;对伴随流星雨出现的一些特殊现象 ,如天空亮度足以掩星盖月、出现极光式的发光现象、大气发声和观测者的心理恐惧等所包容的流星密度和总数 ,也做出估算。 (5)解释中国历史上惟一一次记载的“月如坠地”现象。
